■ Design Considerations

While operating at IF<1.0mA, CTR variation may increase.

Please make design considering this fact.

This product is not designed against irradiation and incorporates non-coherent IRED.

● Degradation

In general, the emission of the IRED used in photocouplers will degrade over time.

In the case of long term operation, please take the general IRED degradation (50% degradation over 5years)

into the design consideration.
